GAS AND AIR MIXER.

To all whom t may concern:

Be it known that I, JOHN D. Russ, a citizen of the United States,residing at Spencer, in the county of Roane and State of lVest Virginia,have invented new and useful Improvements in Gas and Air Mixers, ofwhich the following is a specification.

My invention relates to engines, and the object is to provideimprovements and refinements that will render the engine useful gas withthe air, and a perfect admixture is,

consequently, taken into the explosionchamber of the engine.

Other objects of improvement will appear as the specification proceedsand the nature of the invention more fully appears.

In the accompanying drawings, forming part of my specification, and inwhich like reference-characters denote corresponding parts throughoutthe several views, I have illustrated a form of embodiment of myinvention capable of carrying out the underlying principles thereof; andin these drawings:

Figure I is a central vertical section through my air and gas mixer;Fig. II is a horizontal section on the line 4 4, Fig. I, lookingdownward, or in the 'direction of the arrow.

Referring, now, in detail to the drawings: 1 designates a fuel-chamber,into which gas is led through a port 2/ in a valve-casing 3, having aninternal valve-seat 4, engageable by a manually-operable valve 5, havinga stem 6. The fuel-chamber 1 is provided, preferably nearer the top thanthe bottom thereof, with an internal, horizontally-disposed partition 7,having, preferablyinear its circumference, symmetrically-arranged,arcuate slots 8. It will be noted that the function of the partition 7is that of a battle, as the incoming gases strike the under surface ofthe partition and are caused to spread outward, toward thecircumferential Specification of Letters Patent.

edge of the partition, whence they escape through the arcuate slots 8.It will be seen that the partition or baffle 7 divides the fuel-chamberinto a larger, lower compartment 9 and a smaller, upper compartment 10.

11 is a manually-operable imperforate disk-valve disposed in the uppercompartment 10, and adapted to control the passage of gas from the lowerto the upper compartment. Said valve is connected with a valvestem 12,having a threaded portion 13 engaging the internally-threaded bore ofthe stem 13 of a hollow, open-bottomed throttlevalve 14, havingoppositely-disposed side ports 14, 14 in the side wall thereof, saidvalve being situated in an air-tube 15, communicating, through anaperture 16 in the bottom thereof, with the upper compartment 10 of thefuel-chamber 1. The lower portion of the circumferential side wall ofthe throttle-valve 14 is disposed in said aperture 16, whereby the openbottom of said valve communicates with the upper compartment 10.

The air-tube 15 communicates, at one end thereof, lwith theexplosion-chamber or cylinder 16 of the engine. In the air-tube 15,between the throttle-valve 14 and the working-cylinder orexplosion-chamber 16 of the engine, is disposed the usual check-valve17.

The movements of the throttle-valve 14 are controlled automatically bymeans of a governor-operated crank 18 fast, at one end thereof, to theupper end of the stem 13 of said valve.

In order to prevent back-firing and also to keep the crank-bearing cool,I admit air, in regulable quantities, into the base or crankcase 22 ofthe engine, by means of a pipe 23, provided with a checkor flap-valveand a manually-operable valve or throttle 25.

In operation, the gas enters the compartment 9 through the valve-chamber3 and, striking the baffle 7, is deflected toward the circumferentialedge thereof, whence it escapes through the arcuate slots 8 in saidbaiile. It will be seen that the volume of gas entering the chamber 9is, byv said slots 8, projected into the upper compartment 10 in aplurality of thin streams or sheets, causing an intimate association ofthe gas with the air and a perfect admixture thereof. In the operationof the mixer, the throttle-valve lst is actuated automatically throughthe mechanism above described, to cut ott passage through the tube 5 atthe proper time. Having thus fully described my invention, `what I claimas new and desire to Secure by Letters-Patent oit the United States is:

l. In a gas and air mixer, an air-tube, a fuel-chamber communicating, atthe top, With said air-tube, a partition dividing said fuel-chamber intotwo sections, said partition being provided with arcuate slots disposednear the circumferential edge thereo, and an imperiforate disk-valvedisposed in said fuel-chamber and movable into and out ot engagementwith said partition to control the passage ot gas through said slots.

Q. ln a gas and air mixer, an air-tube haying an opening in its bottoni,a fuel-chamber connnunicating, at the top, Awith Said airtube throughsaid opening, a hollow, openbottoined throttle-valve disposed in saidairtube and projecting, at its bottom, into said opening in the bottomoi' the air-tube, said valve being provided with oppositely-disposedside-ports in the side Wall thereof and being provided, also, with aninternallythreaded stem, a partition dividing said fuel-chamber into twosections, said partition being provided with arcuate slots disposed nearthe circul'i'iferential edge thereof, and an imperiorate disk-valvedisposed in said fuel-chamber and movable into and out of engagementWith said partition to control the passage of gas through said slots,said Copies of this patent may be obtained for said valve being providedwith oppositelydisposed side-ports in the side wall thereof and beingprovided, also, with an internallythreaded stem, means for automaticallyactuating said throttle-valve, a partition dividing said fuel-chamberinto two sections, said partition being provided With arcuate slotsdisposed near the circumferential edge thereof, and an imperforatedisk-valve disposed in said fuel-chamber and movable into and out ot'engagement with said partition to control the passage of gas throughsaid slots, said disk-valve being provided with a partially-threadedstem engaging the internally-threaded portion of saidthrottlevalve.

In testimony whereof l have hereunto set my hand in presence ot twosljlbscribing Witnesses.
